BRUSH MACHINE,

Application filed May 25,

To all trimm t 0n ty concern-f Be it known that l, WALTER C. Fnsi), acitizen of the United States, residing in the town of Bloomfield, countyof Essex, and State of New Jersey, have invented certain new and usefulimprovements in Brush Machines7 of which the following is aspeciiication.

My invention relates to a device designed to hold a wooden blank whichis to become the back of a brush, and iirmly to position this blankwhile it is undergoing certain operations in the course of brushmanufacture. such as drilling the blank with the holes which are toreceive the tufts and subsequently tufting the brush, that is,inserting` the tufts or bristles in the previously drilled holes andsecuring them in place.

My invention aims to perform the various functions attendant uponpositioning and holding the blank in predetermined successive positionswithout manual effort or attention on the part of the operator, all thevarious operations being accomplished automatically by suitablemechanism. vWhile thus doing away with hand labor and thus reducing thecost ol manufacture, my invention also makes possible the further vanceof absolute uniformity in the product, thatA is7 every back will bedrilled with the saine number of holes, positioned exactly the same andof uniform depth, so that if a drilling machine and tufting machine arecoupled together, the blanks after being drilled may be removed from theholder or carrier ofthe drilling machine and placed in a similar carrierof the tufting machine with the definite certainty that the tufts willcentrally enter the holes previously drilled. lvlany other advantageswill become apparent from the following specification.

ln the accompanying drawings. which form a part of this specification7Figure 1 is a front elevation of one embodiment of my invention mountedin connection with a drilling machine of the usual type. Figure 2 is afragmentary view, also in front elevation, of the blank carriers andpart of their operating mechanism at the phase in the operation of themachine when the drill has finished operating on one blank and is aboutto drill a companion blank. Figure 3 is a top view on an enlarged scaleof the carrier mechanism in the position of Figure 1. Fig- 'lV-V ofFigure 3.

- Referring to the drawings in detail, the numeral 1 designates a baseupon which is mounted a frame 2, in which is journaled a shaft 3 uponwhich is loosely mounted a nulley et driven by belt 5. The clutch 6splined to the shaft 3 is adapted to lock the pulley on the shaft andcause the simultaneous rotation thereof. Upon the shaft 3 is mounted agear 7 meshing` with gear 8 on the shaft 9, likewise mounted in theframe 2 and carrying upon its inner end the cams 10 and 11. The cam 11is provided with a. follower 12 (see Figures 5 and 10) mounted upon anarm 13 pivoted at 14 to a fixed part of the framework of the machine andpivotally connected at an intermediate point to an arm 15, which ispivoted at 16 to a bell crank lever 1T. Upon the extending end 1S ofthis bell crank lever is pivoted a pawl 19, which is constantly urgedtoward the lever by means of a spring 20. This pawl is adapted to engageteeth 2l on the periphery of `a wheel 22 fixed to the shaft 23, which issuitably mounted in bearings 25. flach revolution of the cam 11 in thedirection of the arrow in Figure causes the pawl 19 to advance the wheel22 a step equal 'to the length of a tooth and a space between two teethand then returns the pawl to its initial posit-ion,

where it will enter the space between the next two teeth. lt will beseen that the shape of the pawl is such that in moving downward inFigure 10, it will be locked with the teeth of the wheel 22 and willcause the wheel to move with it, while in moving upward the pawl willride over the teeth. rlfhe cams 10 and 1l are so designed and bear Vsuch an angular relationship to each other that at the instant the pawl19 ends its downward travel, that is, when it has advanced the wheel 22a complete step, the wheel will be locked in that position by means of adog 2G carried by a block 27, which has a pin-and-slot connection with alever 28 pivoted to the frame at 29 and having its upper end pivoted toa link 30, which in turn is pivoted t0 an arm 81 mounted upon a rockshaft'32 to which is also secured the arm carrying the follower 311 ofthe cam 10. lt will thus be seen that by the mechanism thus fardescribed the continuous revolution of the shaft 3 gives the wheel 22and the shaft 23 a step-by-step movement equal to the length of a toothand the distance between two teeth.

Mounted in guideways 35 in front of the machine is a vertically slidingarm 36 in which is journaled a chuck 37 of any suitable construction forholding the drill 38. The upper end of the shaft to which the chuck issecured is provided with a pulley 39 over which passes a belt el()running over the guide pulleys al and pulley l2 on shaft e3. This shaftcarries another pulley all, which is continuously driven by the belt l5passing over a pulley @t6 on the shaft 3. By this mechanism the drill 38is continuously rotated 'as long as the shaft 3 revolves. The arm 36 andconsequently the drill are reciprocated vertically@ by mechanisminclud-` ing an arm 4T pivoted to the arm 36 at i8 and at its other endto a bell-crank lever 4:9 centrally mounted upon the frame of themachine. The other end of this bellcrank lever is pivoted' at 50 to theconnecting rod.

inseam consist of a body portion 5?, and a handle 54. rlhe face of thebody portion is customarily curved transversely, shown in Figure l?, andthe tip 55 is curved or beveled ofi shown in Figure 13.

ln the manufacture of a brush of this type, the tufts are usually placedradially with respect to the transverse curvature and while they areperpendicular to the axis of the brush near the handle, as shown inFigures 13 and 16, they" are inclined at an increasing angle as the tipis reached. Furthermore, in order to n'iake the bristles appear uniform,it is necessary to have the tufts closer together at the tip, where theyare inclined sharply away from each other, than near the handle wherethey are more or less parallel. lt will thus be seen that a complexmotion of the blank holder or carrier is necessary, if the drill is toVhave a simple vertical reciprocating movement. Not only must theholderbe capable of a transverse tilting movement about the center ofcurvature of the face of the blank, but it must also be tilt-ablelongitudinally to accomplish the inclining of the tufts required by themutual inclination of the holes in Figure 16and must also be capable ofa movement toward and away from the drill, since the holes are bored toa substantially uniform depth. The carrier must also move back and forthso as to coverl the area of the body of the blank with the desirednumber of holes, and their spacing must be constant and predetermined.The carrier and the mechanism for giving it these complex movements willnow be described.

The blank holders consist of plates 56 and 57 mounted upon. the frames58 and 59, respectively, (see Figures 3, 4 and 7). Each plate isprovided at one side with a stop or guide 60, against which one side ofthe blank isadapted to be seated, and at one end with stops 6l havingbeveled faces adapted to engage the narrowing part of the blank. ilmovable clip 62 forced inwardly by means of springs 63, is adapted to beclamped against the other side of the blank by the wing bolt 6e. It willbe understood that in placing a blank in the machine, the wing bolt 64is retracted suiiiciently to permit the blank to be placed by theoperator in Contact with the stops 60 and 6l. A turn of the wing boltv64 will then be sufficient to clamp the blank between the clip 62 andthe stops, its longitudinal position being determined by the engagementof the stops 61 with the receding ends of the blank adjacent to thehandle. lt will be seen that the plates and the frames to which they aresecured are angularly disposed with reference to each other and that thestops are so arranged that the carrier is capable of holding two blankswith the tips' close together. Each llO of the frames 58 and 59 isprovided with y depending ends having the lower edges 66 formed on anarc and seating upon similarly curved surfaces 67 in a sub-trame 68. Thesurfaces 66 and 67 are held in continuous but slidable engagement bymeans ot pins 69 mounted upon supports 70 secured to the sub-frame andentering grooves 71 in the members 65, these grooves being` formed aboutthe same axis as the surfaces 66 and 67. By this construction, thecarriers and the blanks are capable oi transverse tilting movement aboutthe axis ot the curved surfaces 66. lThe machine is so designed thatthis axis is also the axis of the transverse curvature ot the blank whenit is in position in the carrier. The device for communicating tiltingmotion to the carriers includes pins 72 projecting from blocks slidablymounted in the adjacent end members 65 ot the two carriers andenteringholes in a spool 78 mounted upon rod 74C. This rod is adapted toreciprocate freely in bearings formed in an upward extension of thesub-frame and is secured at its inner end to an arm 75 mounted in andconnecting uprights 76 and 77, the lower ends having a dove-tailconnection at 7 6 and79, respectively, with a fixed portion of the mainframe of the machine. This construction provides a frame which isadapted to slide horizontally in a direction forwardly and rearwardly ofthe machine. The position of this trame and consequently the transversetilting motion of the carrier are controlled by a cam 80 on one face ofthe wheel 22. This cam is provided with a follower 81 mounted on and arm82 secured at its other end to a shaft 83, which is provided with arms81 and 85 pivoted to links 86 and 87, respectively, which are in turnpivoted to the uprights 76 and 77. lt will be seen that the cam groove80 causes the oscillation of the arm 82 and through its linkage producesa reciprocation or the menibers 76 and 77 connected by the arm 75 whichin turn reciprocates the rod 74 and thus tilts the carrierstransversely.

The sub-frame 68 has the general form or" a cross, the top carrying therod k711 and the arms supporting the outer ends oit the carriers. Thiscross is provided centrally with a transverse shaft 90 extendinglaterally beyond the sub-frame on each side and providedl with therollers 91 and 92 resting on the arcuate rails 93 and 94. respectively.T he position of the sub-frame, and consequently of the carriers and theblanks is determined by the following mechanism:

Link 95 is pivoted at 96 to an arm 97 secured to the upper part of oneside oit the sub-trame. rilhe other end of this link is pivoted at 98 toone arm 99 oi' a bell-crank lever, which is pivoted to the frame at 100.The other arm 101 oi' this lever is pivoted to the upper end of the link102, the bottom ot which is pivotcd to an arm 103. The link may beprovided with the turn-buckle Yfor purposes oi adjustment. The inner endof the lever 103 is pivotedly mounted upon the shaft 105. Centrallymounted upon the lever 10T-l is a "'lshalied dog 106, Ywhich is tree 'tomore about the point 107 as an i il" xure 6). lilith the parts in theposition shown in Figure 6, the extending cnil o1 this is thrown to theright into a slot 108 in one arm 109 ot a bell-crank'leve mounted uponthe shaft 105 Figure 11). The other arm 110 of this lever is providedwith a cani roller or follower 111 entering a cam groove 112 in theVface et' the wheel 52 opposite to the cam 60. V11s the wheel 22revolves, it will cause an oscillation of the hell-crank arm 110, andwhen the dog 106 is in the position shown in Figure 6, the other aim 109and the lever 109 are locked together by the dog, and consequently thisoscillation ot the arm 109 will be communicated to the arm 95 throughthe linkage previously described, and this will control the position otthe arm 97 and thereby the upper end of the cross forming the sub-trainefor the carriers. `When, however, 'the dog 106 is thrown to the lei'twith relation to Figure 6, direct connection between the bell-crank arm109 arl the er er will be broken. The dog wi "hen enter a slot in alever 113, which is freely mounted upon the shaft 105 and which has itsend connected by a link 11eL to a bell-crank lever 115 pivoted to theframe at 116. rEhe upper end of this bell-eranlnlere is pivoted at 117to a link Q, w iieh pivoted at 119 to the arm 110. llfhr such connectionis established between the arn 103 and the lever 113, any movemen it thebell-crank arm 110 toward *lie rear o the machine, instead of lifting4the arm 103 villrlepress it, since the connection between the hell-crankarm 109 and the arm 10S has been broken and motion is now communicatedfrom the arm 110 to the arm 10B through li 1, bell-crank lever 115,

iik rie link 1Y et, rever 1123 and dog 106. This mechanism thus affordsan eri-festive means `for causi a reverse movement ot the arm 103' withre'l'erence to the motion of the bell-crank arm 110 merely by shittingthe dog' 106 through small angle.

ne mechanism which controls the action log consists or". a :trameincluding the 120, which span the 'shaped head K6, aid the horizontalconnect- 't 21, 122, the entire trarne being laterally in the main trameoi the machine. The position oi' the frame is controlled by a lever 123pivoted to the main at and having its lower end connected to 'the member121 by a pin-and-slo't connection 125 (see Figure 1) The upper end otthe lever 123 is provided with a wide notch 126, adjacent to which ispivoted a latch 127 (see 11 igure 2li). Projecting rearvxardly 'from thelatch is a pin 128 adapted to move in the notch r1`he upper end of thelatch is connected to the lever 123 by a spring1 12S. lt will be seenthat the latch has two positions oi rest, one in which the pin 123 is incontact `with tue right-hand side ot the notch 126 as shown in Figures 1and 211, and another in Which the latch is svi/ung to the lett with thepin bearing LLinst the lett-hand side of the notch as in Figure Once inevery revolution o1' the wheel ioo mounted upon the shaft 23 the latchis engaged by a pin 131. lt `the parts are in the position shown inligures 1 and 241, the pin 131 vrill strike the upper portion of 'thelatch and Will swing; the upper end oi the lever 123 tothe right. rliisWill throw the lower end ot the lever 123 and consecpaentlg7 the/trameto which it is connectcd to the loft with reference to Figure 1 and Willshift the dog 106 into the position oli Figure 6. Further travel ot thepin 131 will cause it to encounter the lower curved portion oiI thelatch 127, and will throw the latch into its other position, namely,With the pin 128 restingagainst the lett-hand end ot the notch 126, butthis is accomplished Without any further movement of the lever 123. Thisis the position shown in.

lfig'ure rthe nent revolution oi the Wheel will bring the pin 131against the other face oi the latch, first swinging the upper end ol thelever 123 to the left, .vith respect to Figures 1 and 24, and thenmoving the latch about its pivot into the position shown in. theseiigures. t each complete revohition of the Wheel 130 .vhen the pin 131strikes the latch, there Will be amovcment of the trame to which thelever 123 is connected, either to the riadit or to the leit, as the casemay' he, and consequently a reversal of the motion or' the arm 103 withreference to the bell-crank arm 110 and therefore with reference to thecani 112 and its `l'ollovver 111.

'lhe lower end ol the arm o the cross which forms the sub-trame 'tor thecarriers is pivoted at 132 to a link 133, the other end of which ispivoted to a bell-crank lever 131 having; its opposite arm pivoted to alink 135 connected at its lower end to an arm 136 loo, ly mounted uponthe shaiit 1053, which carries a dos` 137 adapted to engage either thelever 133 or the arm 139 ot a bell-crank lever 140 provided at its upperend \.v ith a roller or cam follower 111 entering;` a cam groove 141-2in one 'lace of the Wheel 139.

The inechanism tor operatingthe dool 137 consists ot uprights -113termini;l a part ot the same Ytrame as the uprights 120 and moving; withthem. so that a similar and synchronous reversa-l ot motion isaiiiorded. The lever 133 is connected by suitable linkage including abell-crank lever 1411 (see bell-crank lever 168.

Figure 8) to the upper arm of the bell-crank lever 1410, this backgearing` being the same as in the case oi the mechanism actuated by thecam 112, and providing the saine reversing action.

'l'he rails 93 and 941 are connected by a bar 150 (see Figure and eachis mounted upon a lf-shaped trame pivoted at 151 to a cross-head 152provided With slots 153 in which are mounted bolts 1511V secured to the'main trame ol the machine. This cross head is Vvertically adjustable bymeans of a screvv 1:55 passing through the internally threaded block 156mounted upon the main frame and provided with a hand Wheel 157. Thecrosshead is also provided with an upwardly extending arm 158 (seeFigure 1) which is con ected by the pivotally mounted links 159, 160 tothe rod 90 forming` the axis oi the rollers 91 and 92.

'lhe position ot the rails and their supportingl 'trame with referenceto the axis o' theirpivotal mounting` 151 is controlled by mechanismprecisely similar to that connected to the lower end of the crossforming` the sub-trame. rlfhis consists of a link 161 pivoted to therail 911 at 162 and at its other end to a bell-crank lever 163, thelower end oit which is connected by the link 1611 to an arm carrying thedog` 166, similar in its construction and 'functions to the dogs 196 and137. This dog is adapted to cooperate either with one end oi thebell-crank lever 167 mounted on shalt 105a or with the lever 1which isconnected lby the link 169 to the bell-crank lever 170 pivoted to themain `iframe at 171 (see Figures 6, 8 and 9). The upper arm ot thislever is connected by a link 172 to the upwardly extending arm 173 ot'The arm 173 carries at its upper end a roller 171i which enters andterms the follower oit theV cam groove 175 on the tace oi the Wheel 130opposite trom the cam 1112. The position ot the dog 166 is controlled byuprights 176 which are secured to the uprights 120 and 143 by thconnecting` members 121, 122.

ln the operation of the device, assuming` that the pulley d iscontinuously rotated by the belt 5 and the clutch 6 is engaged, thedrill'Will be rotated continuously by belts l() anc. e5 and pulleys andshafts -with which they cooperate. llach time the cani 11 makes onecomplete rotation, the drill Will be given a complete verticalreciprocation through the bell-crank levers and links which connectthem, since the cams 19 and 11 are mounted on the same shatt and revolvewith it. For each reciprocation et the drill, the wheels 22 and 130`will be advanced one step through the action of the mechanism actuatedby cams 1() and 11 and this interval Will consist of al relatively shortperiod during which the Wheels are being advanced one step by the paivl19 and a relatively long period during which they are locked instationary position by the dog 26. The relation of the cams to the point52 at which the arm 51 is pivoted to the cani 11 is such that it will beduring this period of rest that the drill makes its downward travel oroperative stroke. Consequently, when the drill is making its downwardstroke, the carriers and the blanks held by them are stationary. rlhestep-by-step movement of thewiieels 22 and 130 results in a variety ofmotions being imparted to the carriers through the agency of the fourcams 80, 112, 1112 and 175 and the mechanism which connects them to thecarriers. The cam 80 acting through the arm 82 controls the posit-ion ofthe rod 7/1- in the manner already described and thus causes thetransverse tilting of the carriers, oscillating the blanks about thecenter of the curvature of the faces which are being drilled. The cam112 acting either directly through the bell-crank lever 110 orindirectly through the back gearing including the bell-crank lever 115,moves the arm 103, which in turn imparts motion to the link 95, whichcontrols the position of the upper part of the cross forming part of thesub-frame of the carrier. Coincidently the position of the lower end ofthis cross is controlled by the link 133 actuated either directly orindirectly through its back gearing by the cam 142. l/Vith the top andbottom of the cross thus controlled, the rollers 91 and 92 are free tomove along the rails 93 and 9leXcept as their motion may be limited bythe links 159 and 160 pivoted to the arm 158 of the cross head 152.

Simultaneously, however, the positions of the rails and consequently'the vertical elevation of the center of the cross is controlled by thecam 175 acting through its linkage.

,The compound motion of the carriers may be briefly described asconsisting of a transverse tilting and a tilting about an aXis throughthe center of the cross accomplished by the links 95 and 133 (which mayalso produce a movement of the rollers along vthe rails) and finally amovement of the rails themselves.

In the position of the parts in Figures 1, 5, 7, 8, 10 and 12, themachine is shown operating upon the first row of the right-hand blank.Referring to Figure 12, it will be seen that the machine has finishedoperating on the blank 180, the last hole having been drilled at 181.The carriers were then moved by an operation which will later bedescribed, into the position for drilling hole 182, and then the otherholes drilled in order, the machine being in the act of drilling 183 atthe phase shown 'in these figures. Upon the completion of the first rowwith hole 184;, the blank is tilted to drill 185 and 186 and then thenext two rows, of which these form the end holes, are drilled, the orderof drilling being indicated by dotted lines in Figure 14:. From hole 187the operation is continued and completed in a direct line to finish thefourth row, as shown in Figure 14, this row ending with hole 188, afterwhich hole 189 (see Figure 15) and the last row is drilled ending withhole 190. The carrier then moves the blank into position to drill hole191. it is to be noted that because the last hole drilled in the blankis actually the first hole of the fourth row, this brings the machineinto proper position to jump a minimum distance from the blank 53 to thenew blank 192 (see Figure 18), with which the attendant has replaced theblank 1,80 at the completion of the latter. By having the machinecomplete drilling the blank 53 with the hole 191 instead of the hole190, only a comparatively short jump is necessary to the next hole 193in the new blank. This jump is accomplished at the phase of the machineshown in Figure 11, with the point 194: of the cam 112 acting' to movethe carrier the required distance. Figure 2 shows the parts in theneutral position just as the shift is being made from one blank to theother. Figure 9 corresponds to Figure 11 and shows that the tooth 131 isjust engaging the latch 137 so as to swing the upper end of the arm 123into the left-hand position, thereby shifting the frame including theuprights 120, 1113 and 17 6 to the right. This will reverse the variousmotions which have previously been imparted to the carriers by the threecams 112, 1&12 and 175 through the shifting of the engagement of thedogs 105, 137 and 166 with the various members of their actuatingmechanism. Consequently, whereasthe carrier has been turning in Figure18 in such a direction as to bore the holes 190 and 191 consecutively,it will continue its motion in the same direction and will bore holes193, 195 and 196 in the blank in spite of the fact that the cam 112,immediately recedes toward the center of the wheel 22 after the highpoint 1941 is passed. This reversal of action at the critical instantofpassing from one blank to the other makes it possible to use cams onlyhalf as long as would otherwise be necessary, since the movement of thefollower 111 rearwardly (toward the axis of the shaft 23) as the wheel22 continues to revolve produces the same effect upon the motion of thearm 103 by virtue of the reversing mechanism as though the cam 112continued to increase its radiusthat is its distance away from the aXisof the shaft 23 after the critical point 19e was passed. The same thingis true of the other cams 142 and 175 and their associated mechanism.Consequently, the holes of blank 180 are bored in a sequence reversedfrom that of the blank 53. ln other words, the line of which the hole196 is the first, is completed and then the next two lines are drilledby a zigzag motion, as shown in Figure 20, until the hole 197 isreached, from which the machine jumps to the hole 198, completes thatrow (except tor the iinal hole 199 indicated in dotted lines, whichcorresponds to the hole 191). The last row, be-

niug with the hole 200, is drilled in a straight line until the hole 201is reached from which point the machine goes into position to drill hole199. Before this time, the operator has replaced the blank 53, Which hasbeen completed, with a fresh blank and at the instant the hole 199 isbored, the machine comes back to the position shown in Fir/rufe l1; thatis, with the critical point 19a of the cam 112 acting to throw thecarriers a suilicient distance to swing them to the hole 209 about to bebored in the new'blank 203 (see Figure 20). Then, the pin 131 actuatesthe reversing mechanism and as the hole 202 is bored, reverses themachine into the position in which it initially was, thus completing alull cycle of operations. The dotted lines in Figure l show thecorresponding position for drilling the left-hand blank.

ll/Yhile l lhave illustrated my invention as applied to a machine torboring or drilling` holes in brush backs, it will be obvious that it maybe applied to other uses, as tor instance, by replacing the drill withanyy desired form oi' tufting mechanism for inserting the tuiits orbristles into holes previously bored, and a matter of tact in practice,l have 'found it feasible to use such drilling and tutting mechanisminterchangeably or there may be a plurality of sets oi carriersprecisely similar in all respects and all actuated from a single set ofcams merely by connecting their various pivot'points to each other withlinks, so that when any point, 'for instance 132, ot one carrier ismoved, all Will move simultaneously. lllhere such sets of carriers areprovided, the blank which has just been drilled in one carrier may beremoved and placed in a corresponding carrier ot' an adjacent set, whichis operated upon by a tutting machine instead. of a drill, and the brushautomatically tufted by that machine.

lllhile l have illustrated and described l only one spccilic embodimento1" my invention, l realize that it is susceptible of Wide adaptation,and l do not desire to be limited to the precise mechanism shown anddescril ed.
